Biography
Guido Giannettini was born in Taranto, Italy in 1930, and he was active in OAS support networks during the Algerian War, leading to his 1961 arrest in Madrid, Spain. He later wrote for newspapers before being a paid agent of the Italian intelligence agency SIFAR. In 1965, his colloquium provided the theoretical framework for the "strategy of tension" (the encouragement of political terrorism), leading to him being hired as a secret agent. He had contacts with OAS leader Yves Guerin-Serac for years, and Guerin-Serac would orchestrate the 1969 Piazza Fontana bombing, which started the "Years of Lead" period of political and social upheaval in Italy. Giannettini died in 2003.
